The Texas Instruments OHCI Compliant IEEE 1394b Host Controller driver allows Windows to recognize and communicate with the FireWire controller used to connect compatible IEEE 1394 devices. Listed under Point Grey Research in the 1394 category, this download is intended for systems running Windows 10, 8.1, 7, Vista, or XP; check the package details to confirm compatibility with your specific Windows version and system architecture.

Key Features

• FireWire controller recognition: Helps Windows identify the Texas Instruments host controller and make its IEEE 1394 interface available to connected hardware.
• IEEE 1394b connectivity: Supports communication through the controller with compatible FireWire peripherals, including supported imaging equipment.
• OHCI-based operation: Provides the controller-level support needed for an Open Host Controller Interface device to work with the Windows driver stack.
• Support for device software: Supplies the host-controller connection that compatible applications and peripheral drivers rely on. Point Grey cameras may also require separate camera drivers or acquisition software.

How to Install

1. Confirm your hardware and Windows version. Open Device Manager and locate the controller, usually under “IEEE 1394 Bus host controllers” or “Other devices.” Check its hardware IDs if the name is unclear, and determine whether Windows is 32-bit or 64-bit.

1. Download the matching driver package. Choose the package intended for your operating system: Windows 10, Windows 8.1, Windows 7, Windows Vista, or Windows XP. Do not assume a package for one version will work on another.

1. Prepare for the update. Close applications using FireWire devices and stop any active image capture or data transfers. If System Protection is enabled, create a restore point before changing the driver.

1. Install the driver. Extract the download if necessary and run its installer with administrator privileges. If no installer is included, open the controller’s properties in Device Manager, choose the driver update option, and browse to the extracted driver folder. Follow any package-specific instructions.

1. Restart and verify operation. Reboot if prompted, then check that the controller appears in Device Manager without a warning icon. Reconnect your FireWire device and test it with its usual software. If a camera remains unavailable, check its separate driver, cable, and power requirements.

Common Issues and Fixes

• Install fails or driver won’t load: Windows may reject the Point Grey package due to signing or OS compatibility. Run the installer as administrator, use a vendor-certified build for your Windows version, and avoid forcing the generic IEEE 1394 OHCI driver over the vendor package.
• Device not detected: Confirm the camera is connected with the correct 1394b 9-pin cable, has external power if required, and the host controller is visible in Device Manager. Try another PCIe slot and check BIOS for the 1394 controller.
• Version conflicts with legacy 1394/FlyCapture drivers: Uninstall older Point Grey/FlyCapture and IEEE 1394 drivers in Device Manager, select “Delete the driver software,” reboot, then install one matching driver version only.
